Forming systems
B.E.P. Forming Systems introduces three products to the concrete contracting market that it says will reduce equipment and labor costs while increasing efficiency, productivity, and profits. According to the company, the Eliminator is the world’s first all-aluminum, lightweight clamping forming system and speeds production by as much as 50 percent. The Big Expander, Expanding Filler System, with its built-in capacity to expand up to 32 inches, offers contractors the first-ever, all-in-one forming system; and the Combo Panel and Brickledge System is an innovative solution for quickly forming ledges on poured walls.

Anchors
DBI-SALA, a Capital Safety brand, introduces the Parapet Wall Anchor for personnel working on parapet wall-type structures such as balconies or roofs, and the Freestanding Counterweight Anchor, a non-penetrating anchor for fall protection while performing work on flat roofs or structures. The Parapet Wall Anchor has a unique, non-penetrating design. Installation is a simple, two-step process that involves adjusting the sliding arm to fit over the wall, then reinstalling the detent pin and hand-tightening the screws until snug. This design allows the anchor to be installed and removed without the need to drill and patch holes, avoiding refurbishment cost. According to the company, unlike other anchors, the non-penetrating feature of the Freestanding Counterweight Anchor reduces the possibility of damage to the anchoring structure and completely eliminates costly and time-consuming installation.

High-performance concrete
Lafarge’s new value-added concrete products, Extensia and Chronolia, were developed with scientific knowledge of the behavior of concrete at every stage of production, implementation, and lifespan. According to the company, the products improve construction site working conditions, with each designed to meet a specific challenge in the building sector. Chronolia combines two apparently contradictory features requested by customers: a concrete product that can be transported and handled like conventional fluid concrete, and which, once laid, very rapidly develops high mechanical strength. With conventional concrete, the maximum possible joint-free surface area is 25 meters. Extensia enables the construction of surface areas of up to 400 meters without joints, thus limiting the problem of cracks and their consequent maintenance costs.

Self-consolidating concrete website
The National Ready Mixed Concrete Association (NRMCA) has launched a new website, www.selfconsolidatingconcrete.org, to support the growing interest in high-performance, self-consolidating concrete (SCC). SCC is a highly flowable, non-segregating concrete that can spread into place, fill formwork, and encapsulate even the most congested reinforcement—all without any mechanical vibration. It is a concrete mixture that can be placed purely by means of its own weight with little or no vibration. Adjustments to traditional mix designs and the use of superplasticizers creates flowing concrete that meets performance requirements.

Precast folder and CD-ROM
Tindall Corporation has released a new, illustrated folder and CD-ROM for its total precast, prestressed concrete educational facilities. The "Using Precast Is Academic" folder and interactive CD is specifically designed to help architects, engineers, contractors, school officials, facility managers, and program managers understand the numerous advantages of building with precast. Along with an overview of precast’s features and benefits, the folder includes real-world project profiles that highlight a variety of precast advantages. The accompanying CD offers a more comprehensive review of precast schools, examining all aspects from design flexibility to engineering assistance to cost advantages.

Multipurpose admixture
Sika Corporation’s new multipurpose admixture, Sikament 686, can be used in cast-in-place concrete and precast applications. This admixture establishes the category of multidosage water reducers by providing increased dispersion of water reduction through the entire dosage range. Sikament 686 can be used as a normal (ASTM C494 Type A) water reducer at its lowest recommended dosage, a mid-range water reducer, or as a high-range water reducer (ASTM C494 Type F) at its highest recommended dosage. According to the company, this increased workability is provided with no delay in normal set time.
